You can send a Forms quiz to students using the Assignments feature in Microsoft Teams. Students can take quizzes—and you can grade them—without leaving Teams.
In Microsoft Teams, select the class team where you want to distribute the quiz.
In the General channel, select the Assignments tab. Select the arrow for the Create dropdown menu, then New quiz.
Select an existing quiz or create a new one. Use the search bar if you don't see the quiz you're looking for right away.
Note: If you select +New Form, a new web browser window will open on your device at http://forms.microsoft.com. Create your quiz in Forms, then return to Teams. Your new quiz will now be available to select and distribute.
Once you select your desired quiz, it will appear in your assignment under Resources. Enter the rest of your desired assignment settings, then select Assign.
Students will be able to complete the quiz, and you can grade it, right from Teams.
